I recently bought a Pimoroni Blinkt!I couldn't be more happy with my product.I'm currently using it as a rainbow-like decoration when I'm playing retro games on my RP0 Retropie.I used this code @reboot sudo python /home/pi/Pimoroni/blinkt/examples/rainbow.py & (via 'crotab -e') to automatically turn on my Blinkt when my Raspberry Pi Zero turns on.But my question is, when I turn off my Raspberry Pi, the lights stay on without moving, even when the Pi is completely shutdown.**Is there another line of code to shut them of when the system is off? **Thanks in advance!
